FLUSH-VALVE MECHANISM.

Specification of Letters Patent.

Patented Aug. 1, 1911.

Application filed June 20, 1910. Serial No. 567,880.

To allwhom 'it may concern:

Be it known that I, JAMES M. YoUNo a resident of Pittsbur in the county of Allegheny and State of Pennsylvania, have invented a new and useful Im rovement in Flush-Valve Mechanism, of w ich thefol lowing is a specification.

This invention relates to flushing *valves for tanks of water closets and similar de- VlCeS.

The object of the invention is to provide a flushing valve of simple construction, but which is eifective in operation and cannot readily get out of order.

The invention comprises the construction and arrangement of parts hereinafter de scribed and claimed.

In the accompanyin is a side elevation part y in vertical section showing a portion of a fiushin tank and flushing valve constructed accor mg tothis invention; Fi 2 is a front elevation of the samei-Jiig. 3 1s a horizontal section on the line 3-3, Fig. 1, showing the Valve lifting drawing Figure 1 ring in its lowermost position and with the.

ball valve omitted; and Fig. 4 is a sectional View through the ball valve. 7

In the drawings 1 represents a portion of the bottom of a flushing tank havnig therein an o, ening for receiving the tting 2 of the fiilshing valve. This fitting has an externally threaded ortion 3 extending through the openin 1n the bottom of the tank and receiving t e clamping nut 4. The upper face of the fittin is rovided with a seat 5 for the valve. xten ing upwardly from the fitting is the usual column or overflow pipe 6.

The valve 7 may beof any suitable buoyant construction. Preferably it is spherical in shape, so that it will properly engage the seat irrespective of'the position it is in when it descends. The ball valve shown is of special construction to form a tight closure, comprising an interior filling or body 8 of some suitable light, solid material which is buoyant, such as 00rd,, and which is covered by an impervious and imperforate covering9, such as a thin covering of soft rubber. A ball of this character is exceedingly buoyant, and is also cheap to manufacture on account of the small quantity of rubber which need be used, and is more durable than a hollow rubber ball as it is of' the water.

The means for actuating the valve comprises a ring 12 of such size that when in its lowermost position it surrounds the valve seat 5 and is entirely out of contact with the ball 7, but when lifted engages said ball below its largest diameter and lifts the same from its seat. This ring may be actuated in any suitable way. As shown, it has connected thereto an extension 13 provided with an opening which surrounds the pie or column 6 and is guided thereby. (lbnnected to said ring is the liftin rod 14 which passes through suitable gui cs 15 and 16 on the pipe or column 6, and is provided at its upper end with an eye 17 or similar means for the attachment of a lever or other operating mechanism. The ring 12 is guided thereby in a right line vertically, so that when it drops it always surrounds the valve seat.

The valve 7 is normally held to its seat by the pressure of the water in the tank but as soon as lifted from the seat so as to relieve such pressure said valve immediately rises due to its buoyancy. To guide said valve and prevent its escape when lifted I provide a suitable skeleton frame compris mg a bracket 18, which is an extension of the guide 16, and which has connected thereto a plurality of vertically depending wires or small rods 20. Three such wires or rods are shownand form a three sided cage which prevents the ball valve from escaping through either side or toward the front. that is, away from the column 6. The column 6, or more strictly speaking, the valve actuating rod 14 forms a guide for the ball at the rear and prevents it from'esca-ping in that direction. When the ball rises on account of its buoyanc it passes upwardly in the space inclosed lify the three rods 20 and the actuating rod 14, and gradually drops as the water empties out of the tank. When the tank is empty the ball drops natural] onto the valve seat, and on account 0 its spherical shape forms a tight closure. It remains in this position, due to the water ressure on the same, until again lifted by the ring 12.

The flushing arrangement described is of simple construction, is effective and eflicient in operation, and cannot readily get outof wardly from said fittmg,' a buoyantorder. The valve itself is ,of such construction that a ti ht closure is formed, and said valve is not ble to cells or otherwise get out of shape so as to allow water to leak past the same.

What I claim is:

pipe tareciprocate vertically lifting means arra to engage the' uoyant valve and lift the same from its seat, and). stationary skeleton frame a to guide and confine said buoyant valve. g

2. A flushing valve comprising a fitting having a valve seat surrounding an outlet opening, an overflow pipeyextendmg forming a valve coiiperatmg with said seat and arrangedto close the outlet opening, a liftin' member surrounding the seat and guide by the overflow pipe to reciprocate vertically and arranfed to engagefthe valve and lift the same rom its seat, a bracket from the overflow ro skel eton rame or cage supp y said bracket and arranged to gulde and confine" said valve.-

8. A flushing valve comprising a fitting having a valve seat surrounding anoutle Copies 0! this patent may be obtained (or ed by said brae opening, an overflow pipe extendin upwardly from said fitting, a buoyant valve coiiperating with said seat and arranged to close the outlet opening, a bracket secured to the overflow pi e, a skeleton frame supportet and extending into proximity to the valve seat, a lifting member surrounding the seat and lying below the lower end of said skeleton frame and being guided by the overflow pipe to reciprocate vertically, and a lifting rod secured to said liftin member. 7 U h A flushing valve comprising a fitting having a valve seat surrounding an outlet opening, an overflow pipe extending upwardly from said fittlng, and a buoyant valve coiiperating with said seat and arranged to close the outlet opening, a bracket secured to the overflow, pipe depending rods carried by said bracket an projecting into roxiniity to the valve seat, a lifting memr surrounding'the valve'seat and guided by the overflow pipe to reciprocate vertically and arranged to engage the valve and lift the same from its seat, and a lifting rod secured to said lifting member and guided by said bracket and co'iiperating with the depending rods toform a skeleton frame for confining and guiding the buoyant valve.-
